Description
Die Erfindung betrifft einen Schließzylinder und einen Flachschlüssel für den Schließzylinder mit einem in einer Bohrung eines Zylindergehäuses drehbaren Zylinderkern mit Schlüsselkanal sowie mit Kern- und Gehäusestiften, die als Zuhaltungen von Kerben bzw. Zahnungen an der Schlüsselbrust des Flachschlüssels aus einer die Drehung des Zylinderkernes blockierenden Sperrstellung in eine Freigabestellung verschiebbar sind, wobei der in den Schlüsselkanal hineinragende Teil mindestens eines Kernstiftes, insbesondere des der Öffnung des Schlüsselkanals zunächst liegenden Kernstiftes, an seiner Mantelfläche mit einer in Einschubrichtung des Schlüssels vorspringenden Flanke der Schlüsselbrust eine Eingriffsverbindung aufweist.The invention relates to a lock cylinder and Flat key for the lock cylinder with one in one Bore of a cylinder housing with a rotatable cylinder core Key channel as well as with core and housing pins, which as Locks notches or serrations on the key face the flat key from a the rotation of the cylinder core blocking blocking position can be moved into a release position are, the protruding into the key channel Part of at least one core pin, especially that of the opening of the key channel initially lying core pin its outer surface with one in the direction of insertion of the key projecting flank of the key face an engagement connection having.
Aus der AT 396 957 B ist ein Schlüssel bekannt, der im Bereich seiner Zahnung nächst der Schlüsselreide eine Kerbe aufweist, in die eine ih Einschubrichtung vorspringende Flanke, insbesondere ein Haken hineinragt. Diese meist trogförmige Kerbe der Schlüsselzahnung wird durch den Haken teilweise überdeckt. Der Schlüssel ist infolge dieser Ausbildung nur schwer nachzuarbeiten. Die üblichen Schlüsselkopierfräsen reproduzieren einen falschen Schlüssel. Durch den Zahn wird das Drehmoment zwischen Schlüssel und Schließzylinder sehr gut übertragen, weil die wirksame Barthöhe im Schlüsselkanal jedenfalls die maximal mögliche Größe hat. Der Schlüssel wirkt ferner mit einem besonderen Schließzylinder dadurch zusammen, daß der Haken den zugeordneten Kernstift festhält und so verhindert, daß der Kernstift in eine Gehäuseausnehmung eintaucht und die Drehung des Zylinderkernes blockiert.A key is known from AT 396 957 B which is in the field a notch in his teeth next to the key has, in which a direction of insertion protruding in it Flank, in particular a hook protrudes. This mostly trough-shaped notch of the key toothing is through the hook partially covered. The key is as a result of this training difficult to rework. The usual key copy milling machines reproduce a wrong key. Through the tooth the torque between the key and the lock cylinder transferred very well because of the effective beard height in the key channel at least the maximum possible size. Of the The key also works with a special locking cylinder characterized in that the hook the associated core pin holds and thus prevents the core pin in a housing recess immersed and the rotation of the cylinder core blocked.
Die Erfindung zielt darauf ab, mit einem Schlüssel der beschriebenen Art eine zusätzliche Funktion bei einem speziellen Schließzylinder zu erreichen, nämlich einen in Sperrstellung in eine Gehäusebohrung eintauchenden Kernstift in die Freigabestellung zu bringen und den Kernstift in dieser festzuhalten. Dies wird dadurch erreicht, daß der dem Kernstift zugeordnete, gefederte Gehäusestift mit einem Anschlag zur Hubbegrenzung seines Verschiebungsweges ausgebildet ist, wobei die Stirnfläche des Gehäusestiftes in der Anschlagstellung im Inneren der Gehäusebohrung nahe der Kernbohrung liegt und die Stirnfläche des Gehäusestiftes den Boden einer Ausnehmung bildet, in die der Kernstift in der Sperrstellung eintaucht, und daß die Eingriffsverbindung zwischen Schlüssel und Kernstift mindestens eine Schrägfläche zum Anheben des Kernstiftes aus der Sperrstellung in die Freigabestellung aufweist. Beim Einschieben des richtigen Schlüssels hebt dessen Schrägfläche den Kernstift aus der Ausnehmung im Zylindergehäuse heraus und bringt ihn mit seiner Stirnfläche in die Teilungsfläche zwischen Zylinderkern und Zylindergehäuse. Dadurch kann der Schließzylinder gesperrt werden. Die Schrägfläche kann am Schlüssel im Bereich der vorspringenden Flanke einer Kerbe der Schlüsselbrust nächst der Schlüsselreide vorgesehen sein. Sie kann in technischer Umkehr auch am Kernstift oder sowohl an diesem als auch an der vorspringenden Flanke der Schlüsselbrust angeordnet sein. Es ist zweckmäßig, wenn im Kopfbereich des'Kernstiftes seitlich in der Mantelfläche eine V-förmige Nut vorgesehen ist und die an der Schlüsselbrust angeordnete und dem Kernstift zugeordnete, in Einschubrichtung über eine Schlüsselkerbe vorspringende Flanke als Teil eines hakenähnlichen Zahnes mit einer in die Nut des Kernstiftes eingreifenden und den Kernstift anhebenden Schrägfläche ausgebildet ist. Die Nut kann auch als V-förmige Ringnut ausgebildet sein. Im Zusammenwirken mit dem hakenförmigen Zahn wird der Kernstift durch Auflaufen auf die Schrägfläche aufgegriffen und angehoben. Die Steigung der Schrägfläche und deren Länge ist so bemessen, daß der Hub des Kernstiftes der Tiefe der Ausnehmung im Zylindergehäuse entspricht.The invention aims with a key of the described Sort of an additional function at a special To reach the lock cylinder, namely a locked position into a housing bore core pin into the Bring release position and hold the core pin in this. This is achieved in that the core pin assigned, spring-loaded housing pin with a stop for Stroke limitation of its displacement path is formed, wherein the end face of the housing pin in the stop position is inside the housing bore near the core bore and the end face of the housing pin the bottom of a recess forms, in which the core pin in the locked position immersed, and that the engagement connection between keys and core pin at least one inclined surface for lifting the Core pin from the locked position to the release position having. When the correct key is inserted, it lifts Bevel the core pin out of the recess in the cylinder housing out and bring him in with his face the division area between the cylinder core and the cylinder housing. This allows the locking cylinder to be locked. The sloping surface can on the key in the area of the projecting flank a notch on the key chest next to the key chord be. In technical reversal, you can also use the core pin or both on this and on the projecting Flank of the key chest must be arranged.

Eine spezielle Ausführungsform ist dadurch gekennzeichnet, daß ein Taststift in einer Bohrung des Zylinderkernes verschiebbar gelagert ist, die in die Kernstiftbohrung einmündet und daß der Taststift von dem aus der Teilungslage in das Zylinderkerninnere eingeschobenen Kernstift aus dem Zylinderkern in eine Sperrstellung ausschiebbar ist, in der der Taststift in eine Gehäuseausnehmung eintaucht. Damit ist sichergestellt, daß eine Freigabe durch den hier in Rede stehenden Kernstift tatsächlich nur in einer einzigen Verschiebelage erfolgt. Wird Teilung nicht erreicht, dann blockiert der Zylinder, weil der Kernstift noch in die Ausnehmung eintaucht. Wird der Kernstift über die Teilung gehoben, dann drückt er den Taststift seitlich in eine Gehäuseausnehmung hinaus und der Zylinder ist neuerlich blockiert. Um ein sicheres Sperren zu gewährleisten ist es zweckmäßig, wenn der Kernstift in Ausschubrichtung aus dem Zylinderkern durch eine Feder vorgespannt ist. Der für einen Schließzylinder der beschriebenen Art vorgesehene Flachschlüssel weist Kerben und Zahnungen an der Schlüsselbrust auf und im Bereich der der Schlüsselreide zunächst liegenden Kerbe ist eine die Kerbe teilweise überdeckende und in Einschubrichtung des Schlüssels vorspringende Flanke mit einer Schrägfläche als Teil eines hakenähnlichen Zahnes vorgesehen. Ein solcher Schlüssel ist mit den üblichen Kopierfräsen für die Schlüsselzahnung nicht reproduzierbar.A special embodiment is characterized in that that a stylus is slidable in a bore of the cylinder core is stored, which opens into the core pin bore and that the stylus from the position of division into the inside of the cylinder inserted core pin from the cylinder core can be pushed out into a locked position in which the stylus immersed in a housing recess. This ensures that a release by the person in question here Core pin actually only in a single sliding position he follows. If division is not reached, the cylinder locks, because the core pin is still immersed in the recess. If the core pin is lifted over the division, it presses the stylus laterally into a housing recess and the cylinder is blocked again. To secure locking to ensure it is useful if the core pin in Extension direction from the cylinder core biased by a spring is.

In den Zeichnungen ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Fig. 1 zeigt einen Längsschnitt durch einen Teil eines Schließzylinders in der Sperrstellung, Fig. 2 den Schließzylinder nach Fig. 1 mit einem passenden Schlüssel in der Freigabestellung und Fig. 3 den Querschnitt zu Fig. 2.In the drawings is an embodiment of the subject matter of the invention shown. Fig. 1 shows a longitudinal section by part of a locking cylinder in the locked position, Fig. 2 shows the lock cylinder of FIG. 1 with a matching key in the release position and Fig. 3 den Cross section to FIG. 2.
Ein Schließzylinder umfaßt ein Zylindergehäuse 1 mit einer
Kernbohrung, in welcher ein Zylinderkern 2 drehbar gelagert
ist. Fünf, sechs oder sieben Reihen von Kern- und Gehäusestiften
sind bei üblichen Schließzylinderkernkonstruktionen
in radialen Bohrungen verschiebbar angeordnet und werden aus
einer Sperrstellung durch den passenden Schlüssel derart verdrängt,
daß die jeweiligen Berührungsflächen der Kernstifte
mit den Gehäusestiften in der Kernbohrungsfläche liegen. Die
Verschiebung der Kern- und Gehäusestifte erfolgt durch die an
der Schlüsselbrust angeordnete Zahnung bzw. durch die Kerben.A lock cylinder comprises a
Die erste Stiftzuhaltung ist in den Figuren dargestellt.
Sie weicht gemäß der Erfindung von dem oben beschriebenen
klassischen Funktionsprinzip ab. Ein Gehäusestift 3 ist abgesetzt
ausgeführt und wirkt mit einem Anschlag 4 zusammen. Dadurch
ist der Hub innerhalb der Gehäusebohrung 5 begrenzt.
Die Stirnfläche des Gehäusestiftes 3 liegt in der den maximalen
Hub begrenzenden Anschlagstellung (z.B. Fig. 1) etwas gegenüber
der Kernborung zurückversetzt und bildet den Boden
einer Ausnehmung 6 in die der Kernstift 7 gemäß Fig. 1 eintaucht.
Dadurch ist der Zylinderkern 2 im Zylindergehäuse gegen
Verdrehen blockiert. Der Schließzylinder ist gesperrt.The first pin tumbler is shown in the figures.
According to the invention, it differs from that described above
classic functional principle. A
Der Kernstift 7 trägt seitlich - der Öffnung des Schlüsselkanals
8 zugewandt - als Formschlußelement zum Zwecke der
Eingriffsverbindung mit einem Schlüssel 9 (Fig. 2) eine V-förmige
Nut 10 mit einer Schrägfläche 11. Wie Fig. 3 zeigt,
wirkt eine Feder 12 auf den Kernstift 7. Wenn kein Schlüssel
9 im Schlüsselkanal 2 steckt (Fig. 1), dann drückt die Feder
12 den Kernstift 7 aus dem Zylinderkern 2 heraus, bis der
Kernstift 7 in die Ausnehmung 6 sperrend eingreift.The
Ein üblicher Schlüssel mit Kerben und Zähnen an der Schlüsselbrust
wird beim Einschieben in den Schlüsselkanal 8 den
Kernstift 7 und dem Gehäusestift 3 allenfalls noch tiefer in
die Bohrung 5 hineindrücken. Der Schließzylinder kann in keiner
dieser Stellungen gesperrt werden.A common key with notches and teeth on the key face
is inserted into the key channel 8
Der richtige Schlüssel 9 verfügt im Bereich der Schlüsselkerbe
13 über eine in Einschubrichtung über die Schlüsselkerbe
13 vorspringende Flanke 14 auf einem hakenähnlichen
Zahn 15, der die Schlüsselkerbe 13 teilweise überdeckt. Die
Flanke 14 ist als Schrägfläche ausgebildet, die mit der
Schrägfläche 11 des Kernstiftes 7 korrespondiert. Beim Einschieben
des Schlüssels 9 in den Schlüsselkanal 8 gleiten die
Schrägflächen 11 bis 14 aufeinander und der Kernstift 7 wird
gegen die Kraft der Feder 12 angehoben. Wenn der richtige
Schlüssel 9 vollständig eingeschoben ist (Fig. 2), dann entspricht
der Hub der Tiefe der Ausnehmung 6. Somit liegt der
Kernstift 7 zur Gänze innerhalb des Zylinderkernes 2, der nun
im Gehäuse 1 gedreht werden kann (vorausgesetzt natürlich,
daß die hier nicht dargestellten Zuhaltungen auf Teilung gebracht
wurden). Der Kernstift 7 wird in seiner Freigabestellung
festgehalten und es wird verhindert, daß er durch die
Feder 12 in die Ausnehmung 6 oder eine zusätzliche Ausnehmung
im Drehbereich des Kernstiftes 7 gedrückt wird. Ein üblicher
Flachschlüssel würde den Kernstift 7 nach unten drücken, wobei
der gefederte Gehäusestift 3 ebenfalls zurückweicht, ohne
daß Teilung jemals erreichbar ist. Da der Kernstift 7 abgesetzt
ausgeführt ist, kann der Zylinderkern 2 bei Erreichen
der Teilung der nicht dargestellten Zuhaltungen zwar aus der
Grundstellung geringfügig weggedreht werden. Eine weitere
Drehung des Zylinderkernes 2 wird aber durch Anschlagen des
abgesetzten Kernstiftbereichs 7 an der Bohrungswand der Gehäusebohrung
5 blockiert.The correct key 9 has in the area of the
Der Kernstift 7 ist infolge seiner Federung und des exzentrischen
Mitnehmerstiftes 16 drehfest geführt. In der Fig. 3
ist ein Taststift 17 dargestellt, der in einer Querbohrung
zum Schlüsselkanal 8 liegt und der bei über die Teilungsfläche
angehobenem Kernstift 7 von diesem nach außen verdrängt
wird. Der Taststift 17 greift dann in eine Gehäuseausnehmung
18 sperrend ein. Die Bohrung für den Taststift 17 kann schräg
zur Drehachse des Zylinderkernes 2 ausgeführt sein, damit der
Taststift 17 beim Sperrvorgang nicht in die Ausnehmung 6
gleitet. Dies kann auch dadurch verhindert werden, daß der
Taststift 17 in Richtung auf den Schlüsselkanal 8 gefedert
ist. Der Taststift 17 kann zylindrisch oder im Bereich seines
Eingriffs auch als quaderförmiger Schieber ausgebildet sein.The
